Whimzees Hedgehog Dog Treats are all natural dental dog treats that are sure to surprise and entertain your dog. The fun hedgehog shape is not only adorable but also functional. As your dog chews, the grooves and hollows in the surface stimulate blood flow in your dogâs gums while also preventing bad breath and the build-up of plaque and tartar. And while your dogâs teeth are getting support, your pet gets to enjoy a fun and interesting chew that is both physically and mentally stimulating.
